This is a Phase I/II single-center, randomized, placebo-controlled, single-blind, dose-escalation, double-dose administration study comprising two dosing cohorts (Cohort 1: 250 mcg M-001 per injection and Cohort 2: 500 mcg M-001 per injection) with 20 subjects in each cohort receiving either adjuvanted or non-adjuvanted formulations. The adjuvant used was Montanide ISA VG51. Cohort 3 with 20 subjects was administered placebo. After priming with M-001 or placebo, all participants were administered a boost of a conventional trivalent vaccine on day 42.
